HEAD-MIRROR.

' head band and properly: positioned with respect to an electric or other lightso asto re fleet-the rays thereofupon the particular part of the patient to be examined, but particularly for the examination 'ofthe ears, noseand throat. I 1

IThe primary objectof my invention is to provide a device of the character mentioned aving a novel lens carrying plate associated therewith permitting. the use of the same head mirror with various kinds of work'aand also permitting the use of the same by. different physicians accustomed to using lenses of various strengths.

3 A still further object of my invention resides 1' in the provis on of a device of the character described that is simple in construction, efiicient in operation, that is compact and that can be manufactured and placed on the market at a minimum cost.

Other improvements and novel details in the construction and arrangement of the various parts of the head mirror may be 7 brought out more in detail in the description to follow, which, for a .clear understanding of the invention, should be considered in connection with the accompanying drawing, forming a part hereof, and wherein is disclosed, for the purpose of illustration, convenient and satisfactory embodiments of the invention. It is to be noted in this connection that minor changes in the construction and arrangement of the various parts may bemade without departing from the spirit of the invention or the principle of operation of the various parts. In the drawings:

Figure 1 is a rear elevation of my invention looking toward the back thereof, and

Fig- 2 is a detached perspective view of the same.

Referring now more particularly to the drawing, wherein like reference characters designate corresponding parts throughout Specification of Letters Patent.

the several views thereof, 1 designates the head mirror, the face 2 thereof being concave and provided with a reflecting surface the concavity thereof being varied as desired so as to throw the reflected light rays from any suitable electric light or other source of illumination, at any desired distance from I the face 2, it being understood that themirror 1 is designed to be carried by a band in the usual manner for mounting the device on the head of the physician or other person I .using the same for examination purposes or' the like. The back 3 of the plate is con- -vexed and is provided with an internally threaded sleeve extension or enlargement 4:

for a purpose which will hereinafter appear. An aperture 5 is provided concentricallgfif the disk 1, forming a sighting means. pitch of the concave portion may be of any Y degree depending on the focus desired.

A circular lens carrying plate G is proon the enlargement 4; disposed between the central opening 5 and the edge of the mirror with any electric or other illuminating lamp, although it is to be understood that the mirror or reflector can be substituted by any other illuminatingmeans, instead of reflectedge of the circular plate a plurality of openings '8, preferablyequidistantly'spac'ed and concentrically arranged are provided and adapted to receive lenses of various degrees of strength. A thumb screw member 9 provided with a threaded end 10 is adapted to retain the circular plate in rigid position relative to the enlargement 4 by means of the shoulder 11 formed on the screw.

In the use of my improved head mirror, the mirror or reflector is attached to the head by a head band in the usual manner, or in any other preferred manner, the concaved or reflecting surface of the mirror being disposed toward the patient so as to reflect rays from a suitable light source on to the object to be viewed by the examiner, the mirror be ing designed to be adjusted in the proper position through the medium of its connection with the head band, in the customary manner. In each of the openings in the plate, numbered lens members are provided of various strengths. When a certain lens is wanted the thumb screw 9 is loosened and vided with an opening 7 concentrically therev of which is adapted to be rotatably mounted or reflector, the latter of whichis'employed ing the rays from the electric or other light, 1 on to the patient. Adjacent the peripheral the lens carrying plate turned untilthe-lens desired registers (Vii 711213116 opening 5, after which the screw 9 is tightened to retain the same in the desired position and i-insnre against accidental displacement. It is to-be noted thattth'e openings in the plate 61containinglenses are numbered from 1 to 10 inclusive, while the opening clesi gnate d zero (Q), is without a lens, for the use of a per- ;son whose vision ;i-s nor1nal. "Thus, ai'fter *th'e mirrorhas b'eenadjusted to reflect the rays f'fromza suitable "lightsourceon to the obj ect tozhewiewed or examined, or when the light trays ifrom -an -el'e'ctricor other "illuminating lan p have loreen *cast upon the -'object 'to be viewed :oreXanii-ned, the -lens' carrying plate .isturned-untiltthedesiredilens registers with *the openingl5,=so that*the;proper vision is obtained,.and in this way; a;.prop er and -thorou gh exa'in inaitionfis permitted -and the device adapted iforuse loy persons with different visions or in. such ,a-ma'nner -as to'render "the object :visible inthe desired way, as for instancefiby magnifying it.

Having ifiill-y described my invention, what I- deems new and. desire "to secure by 'TLetters Patent, is

"1. The combination with a light reflector having v(a peep opening or a circular plate 'JSIII'illlQIiilhfiiIlf-Sfllll reflector and turnably supportedatiits arile on the-refiectonsaid plate {having a plurality "of spaced concentrically 'ztrrangedpp'enings ith-erethrough --adapted to be successively -hrou'g'ht --i-nto eal-ineinent with '-.fthe"openin'giofthe reflector, one of said-openjngs being -unobscured and lenses in-the remaining ropen'ings, of different values.

2.
